I've been a fan of Louie Psihoyos for a long time as a National Geographic photographer and guy with a big conscience who wants to make a difference in the world. I loved seeing him win his Academy Award for Best Documentary, The Cove.
I've also been fascinated for a long time with the competing theories of food as it applies to sports performance and health. It feels like 95% of the public believes protein is essential and the best source is meat. It also felt like 95% of credible food scientists believe the best source is plants.
I don't know why more people aren't obsessed like I am because so much depends on it: Olympic medals, Superbowls, heart attacks, weight, erectile dysfunction — and even the macro question of why the majority of people believe something very different than what so many scientists believe.
So when Louie agreed to direct Game Changers and James Cameron agreed to produce it, they had my attention. I've watched a lot of smaller budget docs on health like Forks Over Knives, but the big guns were coming to the party this time.
The star of the show is actually former UFC fighter, James Wilks, who co-wrote and narrated it. I didn't expect him to be so knowledgeable and present so well. Seems like a perfect personna for the job because he's badass and likeable.
In my opinion, the best parts of the film were like high school science class experiments. Great science teachers do fascinating demos in class you never forget. In this film, they took young, model-of-health pro athletes and fed them a burrito with either chicken or beef in it. Two hours later they took blood samples and centrifuged them to separate out the plasma and show how the fat bomb exploded into their bloodstream and created inflammatory markers.
The next day they gave them bean burritos and showed them how dramatically different their blood became.
They did the same, tastefully, with erections. I know, awkward, but it was a hilarious part of the film and super convincing.
Plant based athletes like Tom Brady are beginning to turn heads with their performances and I loved that part of the film. They got to interview a lot of them. This guy was my hero, tho. He's 60 and does pullups like buttah:
